3. Standards – why?
Standardization, is there need for standards? The introduction of LEDs into the lighting market has and is making manufacturers and users rethink their lighting needs, test methods and the application of their existing equipment. The rethinking is helped along its way due to the world-wide energy shortage and in particular here in South Africa.
The goals of standardization can be to help with independence of single suppliers (commoditization), compatibility, interoperability, safety, repeatability or quality.
Standards ensure desirable characteristics of products and services such as quality, environmental friendliness, safety, reliability, efficiency and interchangeability and at an economical cost.

4. Standards - types
Standards for products are broadly divided into two categories namely that of Safety and Performance.
Safety - Safety standards deal with the requirements that will ensure that the products are safe and will not cause harm to the user or the user’s building when used as recommended. Safety standards offer the tests and test methods to verify that the products are compliant. These safety standards may cover a wide range of products.
Performance - Performance standards deal with the way that the product performs under a test situation. However as quote from Wikipedia, “The existence of a published standard does not necessarily imply that it is useful or correct. Just because an item is stamped with a standard number does not, by itself, indicate that the item is fit for any particular use. The people who use the item or service (engineers, trade unions, etc.) or specify it (building codes, government, industry, etc.) have the responsibility to consider the available standards, specify the correct one, enforce compliance, and use the item correctly. Validation of suitability is necessary.”

5. LED Standard Terminology
The IEC has published some Standards and two Public Available Specifications (PAS). The need for the PAS documents is because these have not been accepted as full Standards but have information that is very useful.
These documents suggest that the following quality criteria should be considered when evaluating LED manufacturer’s claims:
a) Rated input power
b) Rated luminous flux
c) LED luminaire efficacy
d) Luminous intensity distribution
e) Photometric code or the values of the next four measurements
f) Correlated Colour Temperature (CCT)
g) Rated Colour Rendering Index (CRI)
h) Rated chromaticity co-ordinate values both initial and maintained
i) Lumen maintenance code
j) Rated life (in h) of the LED module and the associated rated lumen maintenance (Lx)
k) Failure fraction (Fy), corresponding to the rated life of the LED module in the luminaire
l) Ambient temperature (tq) for a luminaire

12. LED Standards required
LED replacements for 50 mm diameter Quartz Halogen lamps – Dichroic lamps
LED floodlights lamps – replacement for PAR W
LED floodlights lamps – replacement 300W 500W 1000W linear quartz halogen lamps
LED linear lamps – replacement for 600mm, 1200mm, 1500mm tubular fluorescent lamps
LED luminaires for above, and
High bay luminaires
Street lanterns

13. LED replacements for 50 mm diameter Quartz Halogen lamps – Dichroic lamps
Eskom Standard used in the Residential Mass Roll out (RMR) based on IEC Self-ballasted LED Lamps for General Lighting Services >50V, Performance Requirement (edition 1)
Needs to be amended
Light output is to be added to be consider for a rebate
50W QH lamp replacement lamp shall have a light output of 600 to 800 lumens
35W QH lamp replacement lamp shall have a light output of 300 to 500 lumens
Tolerance allowed 5% and the power of the lamp used to calculate the rebate.
Colour of lamps warm white 2800 plus tolerance ±7%
Other?

14. Intensity, Beam angle and Colour
Warm White
Cool White
Pure White
Quartz Halogen White

15. LED floodlights lamps – replacement for PAR W and LED floodlights lamps – replacement 300W 500W 1000W linear quartz halogen lamps
Existing IEC LED lamp standards could be used.
Mass of LED lamp is high and the lamp holders should be checked.

16. Replacement lamps 1550 grams and 800 g
Note LEDs on top of left not burning and the heat sink material

17. LED linear lamps – replacement for 600mm, 1200mm, 1500mm tubular fluorescent lamps
These have the same challenges as the T5 retrofit and the SANS/IEC should be amended to include the G13 lamp cap but there is an IEC draft for LED tubular lamps and this is recommended to be used.
The IEC LED draft offers a better solution as it looks at LEDs and their test systems.
Test facilities may need to be arranged and hence if this is used as a guide or ARP and later become a VC

18. IEC draft Double-capped LED lamps for general lighting services –Safety specifications
1 Scope
This International Standard specifies the safety and interchangeability requirements, and the
exchange operation together with the test methods and conditions required to show compliance of
double-capped LED lamps with caps G5 and G13, intended for replacing fluorescent lamps with the
same caps, having:
– a rated power up to 60 W;
– a rated voltage of up to 250 V;
Such LED lamps are designed for replacement without requiring any modification of the luminaire.
The existing luminaires into which the double-capped LED lamps are fitted, can be operated with
electromagnetic or electronic control gear.
The requirements of this standard relate only to type testing.
Recommendations for whole product testing or batch testing are given in Annex A.

19. Typical information 5.3.2 Graphical instruction (IEC Draft)
This clause can be used instead of The steps of applying the product to an existing luminaire shall be as given in Figure 8.
Switch off – remove - replace - connect - switch on
Figure 8: Schematic steps of removing a fluorescent lamp and inserting a double-capped LED lamp
Note no safety circuit shown – SA will require a safety fuse this is in the text of IEC draft

20. Proposed Guide lines LED Tubular lamps
Use the T5 retrofit guide lines as the min basis
Labels three off positions in retrofit
Circuit diagrams shown with changes
Luminaire tested with lamps especially retrofit
LED replacement lamps not recommended for emergency luminaires as a refit but recommend new luminaires are used here.
Zone classified luminaires must be retested with the LED lamps and certificates provided.
All luminaires tested to have photometric data available .

21. LED luminaires for above, High bay luminaires and Street lanterns
Used the amended SANS/IEC safety and call for SANS 475 testing for performance data.
Phase this is but issue a working guide so that Users can specify correctly and manufacturers can compete on an equal basis.
Street light standard is the most urgent followed by high bay luminaires for stores.

22. LED modules – replaceable?

23. Light output and life
All LEDs must state the light output initial value and the value at 1000 hours, 2000 hours and hours.
The LED survival must be 2% failure before 1000 hours 5 % at 2000 hours and not more than 50% AT hours. L70F50 ≥ h=max 50%lamps having lumen maintenance below 70% after hours and L85F05 ≥ 1000h = h=max 5%lamps having lumen maintenance below 85% after 1000 hours
CRI greater than 80
Efficacy NDLS 65 lm/W DLS 55 lm/W and increasing
Ref European LED Quality Charter
Batch testing is required.

24. Electrical – power and power factor?

25. Electrical – power and power factor?

26. Conclusion
This is a quick proposal of ideas but South Africa requires these Standards or guidance so that the local industry can establish themselves, importers can bring in safe and efficient LEDs and products, inter-changeability can be achieved with reliable service for users
Users can specify products fairly and get competitive prices.
Stock holding can be limited

27. Thank you.
